problem in gunzip kernel!

[Terry B. Chen]

I met problem in gunzip my linux kernel:
The message in serial console is :
January 2000, James Hendricks, Dale Webster, and Ron Minnich.
Version 0.1

203:init_bytes() - zkernel_start:0xfff80000  zkernel_mask:0x0000ffff
Searching for 16 byte tags
    64:rom_read_bytes() - overflowed source buffer. max_block = 7
init_bytes found 0 tags
Gunzip setup
gunzip_setup
output data is 0x00100000
Gunzipping boot code
bad gzip magic numbers

I think we may have error in zkernel_start address or there is a Tag in linux kernel we must do something?

Best Regards
Terry Chen

Greetings,

The tags are optional and help when multiple targets are selected. If no
tags are found, the default is to load starting at ZKERNEL_START.

However, if ZKERNEL_START == 0xfff80000, there's not enough room for a
kernel unless you've done something interesting there.
G'day,

no, the problem is that ELF_BOOT is not set to 1. This is the wrong set of 
messages to get. You've got something configured wrong.
